Default 71 Power Steering not working
My power steering slowly stopped working, over a two-month span. Someone on this forum said if you look into the filler port, and do not see any fluid movement, the pump is bad. I saw nothing but a little vibration of the fluid, so I replaced the pump, with one from Napa. Power steering still does not work.

I replaced the control valve 10 years ago. Does anyone have any other trouble shooting ideas?

Put a gauge on control valve to check pressure

The big nut on the back of the pump where the pressure hose connects has a spring and a valve under it. Take the pressure hose off, unscrew that big nut/fitting and make sure the spring is in first and the valve in last over the spring before you screw the fitting/nut back on. If the spring is in last over the valve it will not work at all. Spring must be under valve pushing valve out against the nut/ fitting that holds it all in.
Seen this simple mistake many times, easy fix.

If the pump was replaced to fix the original problem....I would suspect the cylinder or valve...........

Is there a way to test the valve?

You can test for pressure from pump to valve,if good then probably valve, believe you can test ram seperate to isolate parts of system
